-See http://railsexpress.de/blog/articles/2005/12/19/roll-your-own-sql-session-store
+This version of SqlSessionStore properly supports both CGI-based sessions (Rails < 2.3)
+and Rack-based sessions released in Rails 2.3.  For the latest version of +SqlSessionStore+,
+see:

 
 

-Only Mysql, Postgres and Oracle are currently supported (others work,

+
+To install, use:
+
+    script/plugin install git://github.com/nateware/sql_session_store.git
+
+This version also includes the "native columns" feature, which enables +session[:xyz]+
+to map directly to column +xyz+ in the sessions table transparently.  For info,
+scroll down to "Step 4".

+Note: Only Mysql, PostgreSQL, and Oracle are currently supported (others work,

+== Step 4 (optional)
+
+If you want to store certain pieces of data as actual columns in the 
++sessions+ table transparently, simply update the sessions migration
+to include the columns.  For example, if you wanted to store +user_id+
+and +language+ as columns, your migration might look something like:
+
+    create_table :sessions do |t|
+      t.string  :session_id, :null => false, :references => nil, :unique => true
+      t.integer :user_id
+      t.string  :language
+      t.text    :data
+      t.timestamps
+    end
+
+Then, use the "native columns" feature of the specific database driver:
+
+    OracleSession.native_columns = [:user_id, :language]
+
+This will map these columns transparently for you. Simply access them like
+normal columns:
+
+    session[:user_id]  = @user.id
+    session[:language] = @language
+
+And the appropriate columns in the sessions table will be updated for you.
